Page/Page column 48, (2011/08/07)
Disclosed is a long-life organic EL device having high luminous efficiency even after storage at high temperatures. Also disclosed is an aromatic amine derivative which enables to realize such an organic EL device. The aromatic amine derivative is represented by the following general formula (1). (In the formula (1), Ar1 is represented by the general formula (2) below, and Ar2 is represented by the general formula (3) below.)
AROMATIC AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING SAME
-
Page/Page column 68, (2008/06/13)
Disclosed is an organic electroluminescent device wherein an organic thin film which is composed of one or more layers including at least a light-emitting layer is interposed between a cathode and an anode. Since at least one layer of the organic thin film contains a novel aromatic amine derivative, which has an asymmetric structure wherein two different amine units are bonded through a linking group, by itself or as a component of a mixture, molecules are hardly crystallized, thereby improving the production yield of the organic electroluminescent device. This organic electroluminescent device has a long life.

Suzuki Coupling of Chiral 1,1′-Binaphthyl Systems - New Synthetic Routes to Functionalize the 2- and 2,2′-Positions

, p. 701 - 709 (2007/10/03)
1,1′-Binaphthyl derivatives 1-5, substituted in the 2- or 2,2′-positions are used in palladium-catalyzed Suzuki coupling reactions. The mono- and bis-borylated coupling components 2, 4 and 5 can easily be prepared and purified, are air-stable and are therefore interesting starting materials for Suzuki coupling reactions with several aryl halides. Thus a variety of new axially-chiral 2- and 2,2′-arylated 1,1′-binaphthyls can be synthesized. Selective monoarylation of 3, 4 and 5 can be performed. Subsequent and stepwise arylation offers general access to unsymmetrically substituted binaphthyls. Moreover, interesting atropisomeric complex molecules, such as 4,4′-bis[2-(1,1′-binaphthyl)]-1,1′-biphenyl (18a), are accessible. Compounds of type 18, which can be obtained by twofold Pd-catalyzed coupling reactions, are of high potential value as ligands or promoters in catalytic, asymmetric processes or as chiral precursor molecules for host-guest interactions.
